Agree, a little time consuming, but definitely delicious!
We also added green onion in the saute, brushed with butter as to not dry out the mushroom, and added breadcrumbs to the top.
Some of the guests thought they were a tad "spicy" but not enough to stop eating them! We had them as a side to a steak dinner.
Great recipe, will use again!

HUGE HIT! :)
My husband and I work at a College, and I baked them for our student leaders at his campus and mine, well, they are all begging for round two!!!
I didn't have the mini-muffin tin, they were fine rolled into a ball with a thumb print before baking. I put the peanut butter cups in the fridge as some suggested, great idea! :) Will make again...as per the begging!!
